Inadequate explication of constructs |
Failure to adequately explicate a construct may lead to incorrect inferences about the relationship between operation and construct. |
|
|
Construct Confounding |
Operations usually involve more than one construct, and failure to describe all the constructs may result in incomplete construct inferences. |
|
|
Mono-operation-bias |
Any one operationalization of a construct both underrepresents the construct of interest and measures irrelevant constructs, complicating inference |
|
|
Mono-method-bias |
When all operationalizations use the same method (e.g. self-report), that method is part of the construct actually studied |
|
|
Confounding constructs with levels of constructs |
Inferences about the constructs that best represent study operations may fail to describe the limited levels of the construct that were actually studied. |
|
|
Treatment sensitive factorial structure |
The structure of a measure may change as a result of treatment, change that may be hidden if the same scoring is always used |
|
|
Reactive self-report changes |
Self-reports can be affected by participant motivation to be in a treatment condition, motivation that can change after assignment is made |
|
|
Reactivity to the experimental situation |
Participant responses reflect not just treatments and measures but also participants' perceptions of the experimental situation, and those perceptions are part of the treatment construct actually tested |
|
|
Experimenter Expectancies |
The experimenter can influence participant responses by conveying expectations about desirable responses, and those expectations are part of the treatment construct as actually tested |
|
|
Novelty and disruption effects |
Participants may respond unusually well to a novel innovation or unusually poorly to one that disrupts their routine, a response that must then be included as part of the treatment construct description |
|
|
Compensatory Equalization |
When treatment provides desirable goods or services, administrators, staff, or constituents may provide compensatory goods or services to those not receiving treatment, and this action must then be included as part of the treatment construct description |
|
|
Compensatory Rivalry |
Participants not receiving treatment may be motivated to show they can do as well as those receiving treatment, and this compensatory rivalry must then be included as part of the treatment construct description |
|
|
Resentful demoralization |
Participants not receiving a desirable treatment may be so resentful or demoralized that they may respond more negatively than otherwise, and this resentful demoralization must then be included as part of the treatment construct description |
|
|
Treatment diffusion |
Participants may receive services from a condition to which they were not assigned, making construct descriptions of both conditions more difficult |
